When Neal sits down to play his first game, he looks at the grey headed Chinese man and says " I know, don't get them wet and don't feed them after midnight" this is a reference to the film "Gremlins" and the Chinaman who sold the 'pet'.
When Neal and Burke hide in the warehouse, the title on the coffee is in Hebrew.
Neal escapes from the Chinese casino by hiding along a rolling tabletop which may be a reference to Indiana Jones in the temple of doom escaping a Chinese casino hiding behind a rolling gong
